Traceability is no longer a new concept for global supply chains. Many organizations already track products, batches and movements across production and distribution. What is changing is the expectation: companies must now prove that these events are reliable, verifiable and consistent across multiple actors.
As supply networks become more interconnected, traceability sits at the intersection of compliance, sustainability, brand protection and data governance. This is particularly relevant for sectors such as fashion, beauty, retail and manufacturing, where transparency around origin and lifecycle management is becoming both a competitive advantage and a regulatory requirement.
Beyond Visibility: The Need for Verified Data
Traditional traceability systems are often based on centralized databases or separate platforms managed by different stakeholders. While these systems can provide operational visibility, they often create challenges when information must be shared, aligned or verified across organizations.
In complex, multi-tier supply chains, data can be duplicated, incomplete or altered over time, making it difficult to maintain a single reliable version of events. This becomes particularly critical in sectors involving regulated goods, sustainability claims or high-value products, where demonstrating origin, handling and chain of custody is essential.
Blockchain is increasingly being explored as a way to address this gap — not by replacing existing systems, but by adding a trusted layer that strengthens the credibility of traceability information.
Blockchain as a Trust and Governance Layer
Rather than relying on a single central authority, blockchain enables a shared and secure record where key traceability events can be registered and verified over time. Once recorded, information cannot be modified without detection, strengthening transparency and accountability.
In modern traceability architectures, blockchain is used to certify key events, timestamps or references to data, while detailed operational information remains stored in existing enterprise systems. This approach allows organizations to demonstrate that specific information existed at a given moment and has remained unchanged over time, while still protecting sensitive operational details.
In the infrastructures developed by SAIT via 1TrueID, blockchain acts as a governance layer that certifies supply chain events strengthening trust in traceability data without disrupting established processes or IT systems.
Capturing Reliable Events at Source
While blockchain enhances data integrity, the reliability of traceability ultimately depends on how accurately events are captured in the physical world.
For this reason, the blockchain-based traceability system developed by SAIT is combined and integrated with RFID, NFC and serialized QR codes, which link physical items to their digital identities. These technologies improve the accuracy and consistency of data captured at source, strengthening the overall reliability of traceability records.
Together, these technologies ensure that every key interaction — from production to post-sale — can be securely connected to a product’s digital identity, creating a transparent and verifiable lifecycle record.
Digital Identity and Product Engagement
One of the key outcomes of blockchain-based traceability is the ability to assign each product a persistent and verifiable digital identity that connects the physical product with trusted lifecycle data.
In sectors such as manufacturing, fashion, beauty and retail, digital identities enable new value beyond traditional traceability. They support product authentication, trusted reselling and transparency across both primary and second-hand markets. At the same time, technologies such as NFC and serialized QR codes enable direct customer engagement opportunities and experiences even after the point of sale.
Through its traceability solution, SAIT enables the creation of digital product identities while supporting emerging initiatives such as the Digital Product Passport.
Looking Ahead
As European regulations evolve, particularly around the Digital Product Passport (DPP), companies are increasingly required to ensure that product information are availabe, reliable and accessible across the entire lifecycle.
In this context, blockchain is a key technology to provide trusted data, with a 100% secure layer that certifies any supply chain events. SAIT technology combines blockchain with RFID, NFC and serialized QR codes, creating a link between physical products and digital identity.
This solution turnes traceability into a powerful driver of brand credibility, assuring transparency and all third parties and customers trust.
